Hi Sudha,

I am not able to reproduce this with RadListView. This issue appears to be unrelated to UI for Xamarin, but rather is likely due to the way you've added your images to each project.  It is important that you set the BuildAction and that the images are in the correct location in each project.

Go here for a full tutorial on how to add image files to a Xamarin Forms application. You can double check your image files are properly added by just using a single <Image Source="MyImage" /> on a page.

Once you've confirmed your build action and file location are correct, you should see your images.

Tip: 
Your application is far too large (309 MB), you should remove all bin/obj/Packages folders before zipping up the solution. The final zip size shouldn't be more than 200k and it will not be redistributing protected DLLs.

Hello Sudha,

I downloaded your demo and indeed the images are not properly added to the applications (there aren't even any images in the UWP app). 

That tutorial I shared in my last reply will show you how to use images in a Xamarin Forms application.
